Kubernetes uses the oom_score_adj value when defining a Quality of Service (QoS) class for a pod. Another value, called oom_score_adj, allows users to customize the OOM process and define when processes should be terminated. The higher this score, the greater the chance that the process will be killed. The Linux kernel maintains an oom_score for each process running on the host. It is important to realize that OOM Killer may kill a process even if there is free memory on the node. The OOM Killer mechanism monitors node memory and selects processes that are taking up too much memory, and should be killed. OOMKilled is actually not native to Kubernetes-it is a feature of the Linux Kernel, known as the OOM Killer, which Kubernetes uses to manage container lifecycles. More complex cases will require advanced diagnosis and troubleshooting, which is beyond the scope of this article. We’ll provide a general process for identifying and resolving OOMKilled. You can identify the error by running the kubectl get pods command-the pod status will appear as Terminating. Similarly, if overall memory usage on all containers, or all pods on the node, exceeds the defined limit, one or more pods may be terminated. If a container uses more memory than its memory limit, it is terminated with an OOMKilled status. A pod can specify a memory limit – the maximum amount of memory the container is allowed to use, and a memory request – the minimum memory the container is expected to use. Kubernetes allows pods to limit the resources their containers are allowed to utilize on the host machine.

The OOMKilled error, also indicated by exit code 137, means that a container or pod was terminated because they used more memory than allowed.
